Coexistence of the single chain magnet and spin-glass behavior in a cyano-bridged {FeIII2FeII} chain

• One thricyanometallate based chain {FeIII2FeII} has been synthesized.
• Ferromagnetic interaction dominates in them.
• The complex exhibits the coexistence of the SCM and spin-glasses behavior.

A cyano-bridged ferromagnetic {FeIII2FeII} alternating chain {[FeIII(pzTp)(CN)3]2[FeII(imidazole)(H2O)]}·3H2O (1) (pzTp = tetrakis(pyrazolyl)borate) was synthesized via rational design. Crystal structure analysis studies demonstrated that complex 1 had a one-dimensional double zigzagging chain-like structure. Magnetic measurements showed that ferromagnetic interactions dominate in 1 and the AC magnetic susceptibility revealed two limit regimes in accordance with the single chain magnet and spin-glass behavior.

One cyano-bridged based {FeIII2FeII} chain has been synthesized by utilizing the thricyanometallate precursors [FeIII(pzTp)(CN)3]− with the Fe2 + ion and imidazole as an auxiliary ligand. The complex exhibits the coexistence of the single chain magnet and spin-glass behavior.Figure optionsDownload as PowerPoint slide
